[ncl-talk] Counting the number of satellite tracks question

[Laura Fowler]

Hi Srishti:

I assume that grid-points outside the satellite tracks are set to some
missing values. In that case, can you use the "num" function in conjunction
with the ismissing function for the entire month?

Just an idea,
Laura
